3 Pcs Reusable Soft Bristle Flexible Straw Cleaning Brushes for Cylindrical Tubes and Containers, 304 Stainless Steel Nylon

Works far better at low speed with a water coolant solution . No problem on ceramic and granite , stone and cement, chemical resin and tiles .

Great item just what I needed for my projects great value for money highly recommend seller

Nice build but it's a bit wonky. Use a loose but to compensate for the deviation

Doesn't look like the bigger ones from the pictures, just small ones.

the metal could be of better quality, the key broken. DO not buy!

Would be better if it was larger, but works well.

Excellent product Excellent service and quality
